What is expected in the development of ARB?

Arbitrum’s roadmap is focused on growing its ecosystem, enhancing security, and staying closely aligned with Ethereum.

  1. Arbitrum Orbit Expansion (Q4 2025) – Launching permissionless Layer 3 (L3) chains across areas like decentralized finance (DeFi), gaming, and artificial intelligence (AI).
  2. Stylus Upgrade (2026) – Adding support for smart contracts written in Rust and C++, alongside the existing Solidity language.
  3. Security Audit Program (2025–2026) – Offering $14 million in subsidies to help projects pay for security audits.
  4. Governance Overhaul (Ongoing) – Improving decentralized decision-making through DAO votes and Security Council elections.

Deep Dive

1. Arbitrum Orbit Expansion (Q4 2025)

Overview: Arbitrum Orbit lets developers create custom Layer 3 blockchains on Arbitrum’s platform. Currently, over 40 such chains are active, with plans for more than 100 across sectors like DeFi, real-world assets (RWAs), gaming, and AI (Arbitrum Foundation). This expansion targets industries that need fast processing and low transaction fees.
What this means: This is positive for ARB because more Orbit chains mean more network use and fee income. However, there’s competition from other Layer 2 and Layer 3 solutions, such as Optimism’s Superchain.

2. Stylus Upgrade (2026)

Overview: The Stylus upgrade will allow smart contracts to be written in Rust, C++, and other programming languages, in addition to Solidity. This opens the door for developers familiar with traditional programming languages (Web2 developers) to build on Arbitrum (CoinMarketCap).
What this means: This is somewhat positive. The success depends on how well the new tools work, but if done right, it could significantly grow Arbitrum’s decentralized app (dApp) ecosystem.

3. Security Audit Program (2025–2026)

Overview: The Arbitrum DAO approved a subsidy of 30 million ARB tokens (about $14 million) to cover 50-100% of security audit costs for eligible projects. An oversight committee will manage this program to help reduce the risk of hacks and bugs (The Block).
What this means: This is good for building trust in the ecosystem over the long term. However, if audits find serious problems, it could temporarily hurt confidence. The program’s effectiveness depends on careful selection of audit firms.

4. Governance Overhaul (Ongoing)

Overview: The Arbitrum DAO will elect new Security Council members in January 2026. Emergency proposals will require 9 out of 12 votes to pass. The community will continue to manage the treasury and protocol upgrades (Arbitrum DAO FAQs).
What this means: This is neutral. Decentralized governance adds legitimacy but might slow down urgent decisions during critical moments.

Conclusion

Arbitrum’s roadmap strikes a balance between technical growth (Orbit and Stylus upgrades), security improvements (audit subsidies), and governance development. While ARB’s price has dropped about 28.7% over the past 90 days, reflecting wider market trends, these upcoming upgrades could boost network activity. Keep an eye on how quickly Layer 3 chains roll out and whether developers start using Stylus to build new applications.


What updates are there in the ARB code base?

Arbitrum’s technology got major upgrades in 2024 and 2025, focusing on better compatibility with Ethereum, stronger security, and improved scalability.

  1. ArbOS 40 “Callisto” Upgrade (May 2025) – Aligned Arbitrum with Ethereum’s Pectra update, enabling more advanced smart contract features.
  2. Stylus Activation (Q3 2024) – Added support for Rust and C++ smart contracts, lowering fees and improving security.
  3. BoLD Implementation (2024) – Introduced permissionless fraud proofs to make network validation more decentralized.

Deep Dive

1. ArbOS 40 “Callisto” Upgrade (May 2025)

Overview: ArbOS 40 brought Arbitrum One and Nova in line with Ethereum’s Pectra upgrade. It added support for EIP-7702 (native account abstraction) and EIP-2537 (BLS signatures used in zero-knowledge proofs).

2. Stylus Virtual Machine Activation (2024)

Overview: Stylus, introduced in ArbOS 30, allows developers to write smart contracts in Rust and C++ in addition to Solidity. This reduces gas fees by about 10 times for complex computations.

3. BoLD & Timeboost Upgrades (2024)

Overview:

Conclusion

Arbitrum’s recent upgrades focus on better Ethereum compatibility, giving developers more flexibility, and reducing unfair transaction advantages (MEV). With Stylus lowering barriers for developers who don’t use Solidity and BoLD enhancing decentralization, ARB’s infrastructure is set for wider adoption. Will future upgrades help Arbitrum maintain its lead as the top Ethereum Layer 2 solution?


What could affect the price of ARB?

Arbitrum faces a mix of technical progress and token-related risks.

  1. DAO Governance & Upgrades – Active proposals and tech improvements could boost adoption.
  2. Token Unlocks – 92.65 million ARB tokens ($48.4 million) unlocked on September 16, which may increase selling pressure.
  3. Layer-2 Competition – New competitors like Base are challenging Arbitrum’s leading position.

Deep Dive

1. DAO Governance & Tech Upgrades (Positive Outlook)

Overview:
Since 2023, Arbitrum’s decentralized autonomous organization (DAO) has approved over 60 proposals, including the recent ArbOS 40 “Callisto” upgrade launched in June 2025. This upgrade added features like Ethereum-aligned account abstraction and BLS signature support, which improve developer tools and user experience—important for keeping Arbitrum competitive in decentralized finance (DeFi).

What this means:
Improvements like Callisto lower transaction costs and enable new applications, such as cross-chain apps, which could increase network activity and demand for ARB tokens. The DAO’s $14 million audit subsidy program (Arbitrum Foundation) also helps strengthen security, building trust that could attract institutional investors.

2. Token Unlocks & Inflation Risks (Negative Outlook)

Overview:
ARB tokens are regularly unlocked, with 92.65 million tokens (worth $48.4 million at $0.439 each) released on September 16, 2025. Nearly half of the total 10 billion ARB supply is already in circulation. These unlocks could lead to increased selling if holders decide to cash out.

What this means:
Past unlock events, like the $44.6 million release in August, have coincided with a 24% drop in ARB’s price over 30 days. With the Relative Strength Index (RSI) at 37.32, indicating a neutral to bearish trend, ongoing unlocks may slow price recovery until 2026, when token emissions are expected to stabilize.

3. Layer-2 Competition & Market Sentiment (Mixed Outlook)

Overview:
Arbitrum remains the top Ethereum Layer-2 solution by total value locked (TVL) at $2.53 billion and monthly active users at 4.2 million. However, competitors like Base (with 22 million users) and Optimism are gaining ground. The Altcoin Season Index at 69 suggests more investment is flowing into alternative cryptocurrencies.

What this means:
Arbitrum’s integration with Robinhood for tokenized stocks (AMB Crypto) could attract more retail investors and help maintain its market share. Still, Ethereum’s upcoming Pectra upgrade (expected in Q4 2025) might reduce the need for Layer-2 solutions over time.

Conclusion

ARB’s price will depend on balancing ecosystem growth with inflation risks. The Callisto upgrade and partnerships with institutions offer potential upside, but token unlocks and Ethereum’s ongoing development present challenges. It’s important to watch if DAO-led buybacks can offset selling pressure from token unlocks. Keep an eye on weekly trading volume (currently $333 million) and Ethereum’s transaction fees after the Pectra upgrade.


What are people saying about ARB?

The Arbitrum community is caught between hope for a breakout and caution as it faces a key resistance level. Here’s what’s happening:

  1. Strong ecosystem – $2.53 billion in total value locked (TVL) and over 900 decentralized apps (dApps) show its leadership
  2. Price test – Traders are watching the $0.585 resistance level for the next big move
  3. High volatility – Daily price swings of about 17% are challenging holders

Deep Dive

1. @CoinMarketCap: Layer 2 leader shows strong fundamentals

"$ARB powers Ethereum’s top scaling solution with 900+ dApps and DAO governance."
– CoinMarketCap Community (5.5M followers · 1.2M impressions · August 7, 2025)
View original post
What this means: This is positive for ARB because its large TVL ($2.53 billion) and active developer community create ongoing demand for the token.

2. @mkbijaksana: Critical $0.585 resistance test brings mixed outlook

"ARB is testing a key resistance level at $0.585 — a break above could push it to $0.90, but failure might cause it to follow Ethereum’s price down."
– @mkbijaksana (89K followers · 420K impressions · August 24, 2025)
View original post
What this means: The $0.585 level is a make-or-break point. Success could lead to gains, but ARB’s price is still closely tied to Ethereum’s performance.

3. @CoinMarketCap: Buying interest strong but caution advised

"ARB shows strong buying pressure with high volume – could challenge resistance if sustained."
– CoinMarketCap Community (5.5M followers · 980K impressions · August 14, 2025)
View original post
What this means: While increased trading volume signals interest, ARB is still 78% below its all-time high and faces risks from unlocked token supply.

Conclusion

The outlook for ARB is mixed. Its position as Ethereum’s leading Layer 2 solution supports growth, but token volatility and broader market challenges remain. The ecosystem’s TVL has grown 40% year-over-year, which is encouraging. Traders are watching closely for a clear break above the $0.585 resistance level. Keep an eye on the 4-hour RSI indicator and Ethereum’s price, as ARB’s movement often follows ETH’s trends.


What is the latest news about ARB?

Arbitrum is managing token releases and buyback efforts while watching important price levels. Here’s the latest update:

  1. Big Token Release (September 16, 2025) – 92.65 million ARB tokens (worth about $48.4 million) entered the market, raising concerns about too many tokens being available.
  2. Buyback Program (September 17, 2025) – The Arbitrum team is using treasury funds to buy back tokens during tough market times to help support the price.
  3. Price Resistance Holds (September 15, 2025) – ARB’s price is holding steady, with key resistance between $0.45 and $0.49, and technical indicators showing no signs of being oversold.

In-Depth Look

1. Big Token Release (September 16, 2025)

What happened:
On September 16, Arbitrum released 92.65 million ARB tokens, worth around $48.4 million, as part of its regular monthly schedule. This follows a similar release in August, and now about 46% of all ARB tokens are in circulation.

Why it matters:
While these token releases are normal, the timing is tricky because ARB’s price dropped nearly 25% over the past month. This raises worries that too many tokens on the market could push the price down further. However, new demand from Robinhood’s recent support for ARB (Indodax) and activity in decentralized finance (DeFi) might help balance things out.

2. Buyback Program (September 17, 2025)

What happened:
Arbitrum has started buying back its own tokens using funds from its treasury, especially during times when many tokens are released or the market is under pressure.

Why it matters:
Buybacks can show confidence in the token, but since these are funded by treasury reserves (not from profits or revenue), there’s a risk this approach might not last long-term. For comparison, some projects like Jupiter and Hyperliquid use revenue-based buybacks, which are generally seen as more sustainable and natural. (Millionero)

3. Price Resistance Holds (September 15, 2025)

What happened:
ARB’s price is facing resistance between $0.45 and $0.49. The 4-hour Relative Strength Index (RSI), a tool that measures if an asset is overbought or oversold, is around 50, meaning the token isn’t currently oversold.

Why it matters:
If ARB’s price breaks above $0.49, it could signal a positive trend. But if it fails, the price might drop back to support around $0.44. Other indicators like the 7-day MACD suggest cautious optimism but not a strong buy signal yet. (Indodax)

Conclusion

Arbitrum is balancing regular token releases with buybacks while facing technical price challenges. The big question is whether growth in the ecosystem—like the Robinhood integration—will help offset concerns about too many tokens flooding the market, or if ARB’s price will stay stuck in its current range. Keep an eye on trading volume and the project’s revenue for clues on where the price might head next.


Why did the price of ARB go up?

Arbitrum (ARB) increased by 1.46% in the last 24 hours, slightly underperforming the overall crypto market, which grew by 0.58%. This rise matches positive technical signals and renewed activity within the Arbitrum ecosystem.

  1. Technical Rebound – Indicators show ARB may be recovering in the short term after being oversold.
  2. Ecosystem Growth – Rumors about a Robinhood partnership and Arbitrum’s strong position as a Layer 2 solution boost confidence.
  3. Buyback Activity – The ArbitrumDAO is buying back ARB tokens, helping reduce selling pressure.

Deep Dive

1. Technical Rebound (Mixed Impact)

Overview: The Relative Strength Index (RSI), a tool that measures if an asset is overbought or oversold, rose from 24.63 to 37.32 over the past week. This suggests that selling pressure is easing. ARB’s price bounced near a key support level at $0.469, which previously triggered price increases in June 2025.

What this means: Although another indicator called MACD remains negative, the RSI rebound indicates traders are cautiously buying ARB after a 10% drop last week. The 200-day Simple Moving Average (SMA) at $0.393 acts as a psychological support level.

What to watch: If ARB’s price stays above the 7-day SMA ($0.491), it could signal a shift toward upward momentum.

2. Ecosystem Momentum (Bullish Impact)

Overview: There’s renewed speculation that Robinhood might use Arbitrum to tokenize European stocks, which previously caused a price spike in June 2025 (The Block). Last week, Arbitrum processed over $5 billion in stablecoin transactions—the highest among Layer 2 networks.

What this means: Adoption of real-world assets and growing interest from institutions are important factors driving ARB’s value. The network supports over 900 decentralized applications (dApps) with a total value locked (TVL) of $2.53 billion, reinforcing its role as a leading Ethereum scaling solution.

3. DAO Buyback Strategy (Bullish Impact)

Overview: The ArbitrumDAO increased its buyback efforts, repurchasing $2 million worth of ARB tokens in the third quarter of 2025 through its Timeboost fee system. This follows a 450,000 ARB grant to PancakeSwap aimed at improving liquidity (PancakeSwap).

What this means: These strategic buybacks help offset the dilution caused by token unlocks. For example, 92.65 million ARB tokens (valued at $48.4 million) entered circulation on September 16 but had little effect on the price.

Conclusion

ARB’s modest price increase reflects a balance between technical recovery and ongoing broader market weakness (down 24% over the past month). Positive factors like the Robinhood partnership rumors and decreasing exchange reserves (down 362,000 ARB last week) offer potential upside. However, the high fully diluted valuation (FDV) of $10 billion remains a concern.

Key watch: Can ARB maintain support at $0.44 if Bitcoin’s market dominance rises? Keep an eye on updates about the Arbitrum-Robinhood partnership for signs of real-world use.
